Recycled concrete aggregate screening device

Abstract

The invention discloses a recycled concrete aggregate screening device, and relates to the field of concrete recycling equipment. The recycled concrete aggregate screening device is technically characterized by comprising a rack and a vibration hopper located on the rack, wherein damping springs are connected between the side wall of the vibration hopper and the rack, a vibration motor is arrangedon the side, facing the rack, of the vibration hopper, a screen plate with screen holes is arranged on the side, away from the rack, of the vibration hopper, the vibration hopper is obliquely arranged, a cleaning roller is arranged below the screen plate, a plurality of convex teeth meshing with the screen holes are arranged on the peripheral side of the cleaning roller, the axis of the cleaningroller is perpendicular to the inclination direction of the screen plate, a rotating assembly for driving the cleaning roller to rotate is arranged on the inner walls of the vibration hopper, and a driving assembly for driving the vibration hopper and the rotating assembly to move in the inclination direction of the screen plate is further arranged on the inner walls of the vibration hopper. The screening device has the advantage of being high in screening efficiency.

Description

technical field [0001] The invention relates to the field of concrete regeneration equipment, in particular to a recycling concrete aggregate screening device. Background technique [0002] Recycled concrete means that waste concrete blocks are crushed, cleaned and graded, mixed with gradation in a certain proportion, partially or completely replaced by natural aggregates (mainly coarse aggregates) such as sand and gravel, and then added with cement, water, etc. new concrete. Recycled concrete can have the following situations according to the combination of aggregates: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates, fine aggregates are natural sand; coarse aggregates are natural gravel or pebbles, fine aggregates The raw materials are recycled aggregates; recycled aggregates replace part of the coarse or fine aggregates. [0003] The Chinese utility model patent with the notification number CN209379397U discloses a concrete aggregate scr...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: since the recycled concrete aggregate is easy to block the sieve plate during screening, the above-mentioned sieving machine needs to be shut down, and the sieve plate needs to be disassembled for replacement or manually cleaned, resulting in low screening efficiency
